Hello,In the past week I have had red patch develop on my outer wrists and one spot on my thigh. Then the redness darkened and I develep tiny raised bumps that icth briefly. Red patches are darkening furher and look like burises. in the last 72 hours, I have developed the thing on the backs of my knees. the discoloration is 3 to 5x larger then the bumpy rash patch. I when to urgent care last week but all i got was stuff for itching: which is minor and brief.
